Indianapolis - Gov. Mitch Daniels has vetoed a bill aimed at cutting power usage by making Indiana's new commercial buildings more energy-efficient.

The bill would have required the state's fire prevention and building safety commission to adopt one of two energy conservation codes for new commercial buildings by July 2010.

Daniels says he vetoed the bill because the commission is already working to update the code.

But the leader of Indiana's largest environmental group says the law would have led to energy-efficient building codes being adopted faster than leaving the issue to the traditional rule-making process.

Hoosier Environmental Council executive director Jesse Kharbanda says Indiana is moving at a "glacial pace" to adopt a new building code to encourage businesses to install energy-efficient heating and cooling systems, windows and other systems.
